Subject: for the wiki: a __MUSL__ alternative
Date: Thu, 01 May 2014 03:41:19 -0400	[thread overview]
Message-ID: <5361FA9F.2090207@midipix.org> (raw)

Greetings,

Since requests for a __MUSL__ macro still come in every now and then, I 
thought it might be useful to add to the wiki the following text at the 
end of the section "why is there no __MUSL__ macro?"

If you have a situation that (temporarily) requires that you can 
identify the libc being used, consider the following trick: as part of 
your configuration script, locate libc.so, then create a symlink from 
libc.so to /some/temporary/folder/ldd, and finally execute 
/some/temporary/folder/ldd 2>&1 | grep 'musl libc';  Based on the 
outcome, you could then add -D__MUSL__ to the relevant environment variable.

I hope that helps,
zg
